What is a Backflow Preventer and Why Is It Required?

A backflow preventer valve is an addition to your outflow sewer pipe that makes sure that drainage only flows one way. In the case of a reverse flow of water, a backflow prevention device helps to prevent pollution being forced into your home and causing contamination.

A backflow preventer is mandated in Toronto by the Water Supply Bylaw that describes which valve may be best for you. 

What Triggers Backflow?

There are several events that trigger backflow, and two of the more common ones are:

back pressure is when surging water pressure outside surpasses the pressure in your sewage outflow pipe. It can push sewage, or black water, back into your sewage outflow pipe and pollute your home. That could include sewage being pushed up your drains.

this is a type of backflow when pressure in the water supply falls below atmospheric pressure. That creates a vacuum in the lines which can draw black water into your home’s pipes and your home.

Backflow Preventer Installation

Double Check Valve Assembly (DCVA) – a DCVA is useful when the risk of contamination is low risk. We install this when the water pressure is constant and there is a minimal chance of backflow. 

Reduce Pressure Principle (RP) Backflow Preventer – an RP preventer is considered unequaled but is better suited for higher risk situations. While better than a DCVA, it is more expensive. 

Annual Backflow Valve Testing

It is required by the City of Toronto that backflow preventer valves be tested annually. The Water Supply Bylaw states that buildings have backflow prevention testing done once a year and also within 3 days of repairs or changes made to the valve.

Backflow test reports must be sent in to the City of Toronto, but that can be done online. Contact AquaRescue to have a Cross Connection Control Specialist come to your home to complete the test.

Commercial Backflow Preventer

A commercial backflow preventer is important for a surrounding community especially with cross connections or hazardous materials in businesses. Commercial buildings, like restaurants, hospitals, and car washes, are required to have a backflow preventer to assist in protecting public health.

I recently worked with Igor and Vitaly at AquaRescue Plumbing to replace my main plumbing pipe, and I couldn’t be happier with their service! From start to finish, they were incredibly professional, friendly, and communicative. They took the time to walk me through each step of the process, ensuring I fully understood what was being done.

The quality of their work was outstanding, and it was clear they take pride in doing things right. I highly recommend AquaRescue Plumbing to anyone in need of reliable and expert plumbing services. I’ll definitely be working with Igor and Vitaly again in the future!

Igor and his team have become our BFs this summer. Due to the unfortunate rainy summer we had this summer, our house was flooded. Igor and his team installed a sump pump and completed exterior waterproofing on our home. Igor is knowledgeable, detail oriented and is able to explain all plumbing world vocab into terms I could understand. He and his team worked hard to meet deliverables in a timely natter while maintaining care and attention to detail. I highly recommend their services
